Hi,

2.6.21-rc1 fails to boot on my machine. As soon as I switch
from grub the screen turns and remains black with no sign
of Tux or any output.

I've run a git-bisect between 2.6.20 (which works fine) and
2.6.21-rc1 and found the first bad commit to be
#59b8175c771040afcd4ad67022b0cc80c216b866 which seems bizarre
to me since this is a mostly an ARM commit.

I haven't tried to revert this commit because frankly I don't
know where to go from there with a multi-parent commit.

I'm running on on a Asus A8N-VM CSM motherboard with a single
core AMD64 processor, with a nVidia GPU in the PCI-ex slot
using the standard VESA frame buffer driver.

Relevant config's can be found here:

and, later,

I have just discovered 2.6.21-rc1 boots with
pci=noacpi ...

Presumably this regression was caused by the ACPI merge.  Are you able to
capture the dmesg output from the 2.6.20-rc1 boot?  netconsole might be
useful here, thanks.

(You get added to the post-2.6.20 regression list, so you'll be hearing
from us quite a lot for the next month.  Sorry ;))
